ln the drawings wherein for the purpose of illustration is shown thepreferred embodiment of iny invention, the numeral 1 designatesgenerally the substantially reetangular shaped fraine forniing a part ofthe present invention. Bracing inernbers forming a rectangular structuresuch as are illustrated at 2 eirtendbetween the sides and the ends ofthe frame adjacent the top thereof. The longitudinally extending bar 3extends between the end bracing ineinbers in the manner as .clearlyillustrated in Figure 3 of the drawing. Additional bracing bars l areassociated with the fraine at the sides and end thereof and the saineare located below the bracing members 2 and the longitudinally extendingbar The supporting' legs 5 for the rectangular shaped traine' arevadapted to be secured at their lower ends on any suitable supportwithin a boat or the like illustrated at A.

Extending transversely on the france 1 and having the ends thereofjournaled in suitable bearings provided on the franie are the spacedtransmission shafts 6, 7, 8 and 9 respectively. The bearings for theends of each of the shafts are illustrated 10 in the drawings withreference more particularly to Figure 2, Also extending transversely onthe frame 1 intermediate the ends thereof and journaled adjacent itsrespective ends in the bearings 11 is the power or driven shaft 12.Suitable fly wheels 13 are mounted on the respcc: e ends of the drivenshaft 12 and if desired, a drive pulley such as is illustrated at 14 maybe secured to theouter end of the driven shaft in the mannerilliiistii'ated in Figure 2 and for the purposes hereinafter t0 be morefully described.

loosely mounted on the transmission shaft G adjacent the ends thereofand disposed within the sides of the fran'ie 1 are the gear wheels 15and 16 respectively. Similar gear wheels 17 and 18 are loosely mountedon the shaft 7 as are also the'gear wheels 19 and 20 on the shaft 8 andthe gear wheels 21' and Q2 on the shaft 9. The gear Wheels on the shafts6 and 7 respectively are spaced from each other but are arranged inalignment for the purposes to be presently described. The gear Wheels onthe shafts 8 Aand 9 are also arranged in the same manner and for thesame purpose. The hub of each of the gear Wheels above described` isprovided with the ratchet teeth :23 for engagement with the teeth 24 ofthe slidable` clutch which is keyed on the shaft in the mannerillustrated in Figure 7. As is apparent from the construction shovvn inFigure 2, each of the transmission shafts is provided with a pair ofslidable clutches designated by the numeral 25 for cooperation with thetoothed hubs of the gear Wheels mounted on the respective shafts.Collars such as are illustrated at 26 are secured on each of the shaftsfor engagement With the opposite sides of the hub of the gear Wheels forlimiting the sliding movement of the gear Wheels on the respectiveshafts.

rlhe clutches 25 are normally held in engagement with the. ratchet teeth23 by the coil 27 whereby the gear Wheels are adapted for rotation withthe shafts on which the same are mounted.

Extending upwardly from the longitudinally extending bar 3 are thesubstantially U-shaped brackets 28. four of such brackets being providedfor cooperation with each of the transmission shafts. The arms of eachof the U-shaped brackets 28 are provided vvith registering openings forthe purpose of supporting the intermediate portion of each of thetransmission shafts and furthermore provide Va means for cooperationwith the coil springs in supporting the same in position on thetransmission shafts. The upper ends of the arms 29 of-each of theU-shaped brackets extend above the frame 1 and terminate in theoutwardly disposed eX- tension 80, the purpose of Which Will bepresently described. A detent or notch 31 is formed in the outer end ofeach of the extensions as is clearly illustrated in Figure 6. Pivotallysupported intermediate its ends on the outer side of each of the arms ofeach U-shaped bracket is the clutch actuating lever 532. The lower endof each lever engages the respective clutch While t-he upper end thereofprovides a handle for moving the clutch out of engagement with the,ratchet teeth of the respective gear wheel for causing the gear Wheelsto become idle on the` shaft. A locking payvl or dog 33 is carried bythe upper portion of each lever for engagement with the detent or notch31 formed in the extension on the upper end of the arms of the U-shapedbracket for holding the clutch out of engagement with its respectivegear Wheels against the tension of the spring 2.7; An auxiliary leverand handle designated generally by the numeral 34 is associated Witheach of the locking dogs for actuating the same in the manner Well knownin the art.

Mounted on the intermediate portion of the transmission shafts G, 7, 8and 9 respectively are the gear Wheels 35, 3G, 3T and 38 respectively.Each of the last mentioned gear wheels is positioned between the arms ofeach of the U-shaped brackets and for the purpose of locking the gearivheels 35 and 38 on the respective shafts so that the same will rotatetherewith. I provide a paivl and ratchet mechanism designated by thenumerals 39 and 40 for the gears 35 and 38 which are loosely mounted ontheir respective shafts? while the gears 36 and 3? are keyed on theirrespective shafts. rhe gear Wheels 35. 36 and 37 and 38 respectively areof the same diameter as the other gear Wheels mounted on the respectivetransmission shafts.

Extending upwardly from the longitudinally extending bar 3 between thegear wheels and 86 and 3T and 38 are the substantially U-shaped brackets41 and 42 respectively. is each of the last mentioned brackets are ofthe same construction, the description of one is thought to sutiice forthe description of both. Journaled in the upper portion of each of thebrackets 41 and 4Q is the shaft 43. A pinion 44 is keyed to the shaftsupported between the arms 45 of the U-shaped bracket 41 and is adapted.to engage the gear Wheels 35 antL 36 respectively while a similar pinion46 is keyed to the shaft supported between the arms of the Ll-shapedbracket 42 and is adapted to mesh With the gear Wheels 33T and 38respectively. This construction is more clearly illustrated in Figures2. 3 and of the. drawingr. The. upper ends of the arms 45 of each of theU-shaned brackets 41 and 42 disposed outwardly to provide the laterale5:- tensions 4.7 and the ends thereof are slotted as illustrated at 48for the purposes hereinafter to be more fully described.

The centrally located driven shaft 12 has the pinion 49 keyed on theintermediate portion thereof and the same is adapted to mesh With thegear Wheels 3G and in the manner as clearly illustrated in Figures 2 and3 of the drawings. The provision of tliegear Wheels 35, 3G, 87 and 38respectively and the pinions which mesh with the saine provide a trainof gears for imparting rotary motion to the driven shaft 12.

Extending vertically Within the frame and adapted for cooperation Withthe gear Wheels 15 and 17 respectively is the rack bar 50. The oppositelongitudinal edges thereof have the teeth 51 and 52 formed therein forengagement with the teeth in the gear Wheels 15 and 17 respectively inthe manner clearly illustrated in Figure 4; A similar rack bar 53 isdisposed bet-Ween thc lOl) gear wheels 16 and 18 respectively and theteeth in the longitudinal edges in therack bar 53 engage the teeth inthe gear wheels 16 and 18. A similar rackbar 54 has the teeth in theopposite longitudinal edges thereof engaging the teeth in the gearwheels 19 and 21 whereby the rack bar 54; is adapted for verticalmovement between the. gear wheels 19 and 21 and in the same manner therack bar has its teeth in the opposite longitudinal edges thereczzfr ingthe teeth in the gear wheels 20 and 22 respectively. l

For the purpose of guiding the rack bars in their verticalmovementsbetween the respective gear wheels ot the transmission shaft,the inner opposed faces of the rack bars are provided with thelongitudinally extending ribs 56, the same operating in the slots 18formed in the outer ends of the eX- tensions 47, the latter beingprovided on the upper ends of the arms of the U-shaped brackets 41 and42. A pair of guide plates 57 are secured to the under side of thelongitudinal bar 3 and extends transversely thereof, the ends of each ofthe plates eX- tending beyond the edges of the bar and are slotted inthe manner shown more clearly in Figure 5 for cooperation with the ribson the inner opposed longitudinal faces of the rack bars.

Engaging the outer longitudinal faces of the rack bars are the. rollerbearings 58 which are supported on the top of the frame l and similarroller bearings 59 are supported on the bracing menibeis 4l which.extend longitudinally between the supporting legs rl`he roller bearingsalso provide a guide means for the rack bars in a vertical movement andeach of the roller bearings comprises a plurality of rollers which areloosely mounted on the shaft 60, the ends of which are journaled insuitable brackets 61. ylhe roller bearings may further provide a meansfor lubricating the outer longitudinal sides of the rack bas to permitthe easy verticalmovement of the rack bars within the frame. l

Arranged transversely on the respective ends of the frame is asubstantially rectangular shaped frame 62. As each of the frames is ofthe identical construction, the description of one is thought to suliicefor the description of both. The transverselyV extending frames aresecured at their respective ends to each other by means of a cross strip63. The frames are adapted for vertical adjustment of theJ ends of themain frame by means of the screw 64 which extends throughthe-longitudinal side members of each of the auxiliary frames 62 andthrough the lugs 65 carried by the ends of the frame 1. A handle 66 isprovided on the upper end of each of the screws for rotating the samewhereby the auxiliary frames may be raised or lowered with respec't tothe main frame. the purpose ot which will be presently described.Cooper@ ating guide means 67 and 68 respectively are associated with theends of the main frame and the longitudinal members of the auX- iliaryframesin the mann clearly illustrated in Figure 2 of the drawingswhereby the auxiliary frames may at all times maintain a substantiallyhorizontal position with respect to the main frame and the supportinglegs therefor. Y

Extending across the top of the auxiliary frames adjacent the endsthereof and journaled in suitable brackets 69 are the shafts 79. Thelevers 71 and 72 lare supported intermediate their ends on the shaft '70and the inner ends of these levers are connecte-d. to the upper ends ofthe rack bars 53 and respectively while the levers 73 and 74 which aresupported intermediate their ends on the shafts adjacent the oppositeends of the auxiliary frames and on the opposite side of the main framel are connected at their inner ends to the upper ends of the rack barso0 and all respectively. The connection between the inner ends of eachof the levers and the upper end of the respective rack bars isillustrated generally at 75 in Figure 5 of the drawings.

,Cooperating with the outer ends of the several levers are thevertically extending rods 7 6 on the lower ends of which are carried thefloat or buoyant members 77. For the purpose of adjustably securing therods in the outer ends ef the levers, the collars 7S are associated witheach of the rods on opposite sides of the lapertured plates 79 eX-tending outwardly from the outer end of each of the levers and suitableset screws 80 secure the collars in locked engagement with each of therods 76 in the manner clearlyy illustrated in Figure 8 of the drawings.

The operation of my improved wave inotor may be briefly sta-ted asfollows-The auxiliary frames 62 are adjusted on the main frame so .thatthe levers may be disposed at the desired angle, depending of course onthe conditions of the water as well as the tide. lith the parts arrangedas shown in the drawings, when the waves strike the floats 77, the samewill cause the rods to move upwardly causing the inner ends of thelevers to move downwardly and simultaneously imparting a downwardmovement on the rack bars whereby certain of the gear wheels which havethe teeth meshing with the teeth on the downwardly moving rack bars willbe rotated thereby and causing the rotation of the train of driven gearsto impart a rotary motion to the driven shaft 12. It is also to beunderstood that when the floats and rods descend after the waves recede,the upward movement of the inner ends of the levers associated with thedescending rods and floats will raisejthe respective rack bar andfurther transmit rotary motion to the driven shaft 12 through the trainof gears and the transmission shaft.

The rise and fall of each Heat while causing a corresponding oscillatorymovement of the driving gear through the mediumof the reciprocating rackbar associated ,therewith also causes a rotary movement in one directionof the driven shaft. rlfhe ratchet mechanism associated with theugearwheels 36, 37 and 38 respectively ,will insure the rotation of thetransmission sha-ft in one direction whereby the positive operation ofthe driven shaft and the fly wheels carried thereby will bev maintained.

It is also to be understood that eachiioat has a weight IV associatedtherewith so that each of the floats will be of a weight equal to twicethe weight of its respective'racl bar whereby the same will operateefficiently at all times and the proper balance between the iioats andthe rack bars will be maintained.

1Whether the operation of the float is simultaneous or successive, theaccumulated impulse is imparted to the device being driven by the pulleywheel 15, each` float receiving a motion which commensurates with themaximum movement of the waves.

Itl will thus be seen from the foregoing description, that a wave motorhas been provided which utilizes the movement of the waves in providinga means for operating machinery or generating electric power in a simpleand efficient manner, the parts being so arranged as to enable the sameto be readily accessible without the loss of any considerable length oftime and labor.

IVhile I have s hown the preferred embodiment of my invention, it is tobe understood that various changes in the size, shape and arrangement ofparts may be resorted to without departing` fromthe spirit of theinvention and the scope ofy the appended claims.

Having thus described the invention, what I claim is l. In a wave motor,a. frame comprising an upper rectangularportion, a lower rectangularportion, legs connected to the portions a't their corners, barsextending between thelegs parallel to and below the longitudinal sidesof the lower rectangular portion, .a third bar disposed between the endsof the lower portion, a plate attached to the lower surface of saidthird bar and having notched ends extending beyond the sides thereof, aU-shaped bracket supported on the upper surface of said third bar andhaving offset outwardly disposed` notched ends, bearing rollerssupported on the sides of the upper portion and on the firstmentionedbars, rack bars having ribs slidably received in the notchesand having their opposite surfaces in engagement with the rollnieansfortaking power from the rack bars, and wave operated means forreciprocating the rack bars.
